Hi there,
I've recently played your game. Here are my thoughts to add to the chaos.
This one was fun. It also ran flawlessly for me (I even tried to see if the collision detection could be tricked into letting me go to higher grounds but it held up). The ambience music was a nice touch.
I wish the bubble activated by toggle rather than hold though. And it would have been nice to visit undiscorded Ponyville after winning (with the bubble magic reverting to discorded Ponyville).
